SEATTLE (AP) -- The chairman of the National Transportation Safety Board says the bridge collapse in Washington state is a wake-up call for the nation.
Debbie Hersman says transportation officials need to study carefully the Interstate 5 bridge over the Skagit River and learn from it.
Investigators need to find out what happened in Washington and if it could be repeated at similar bridges around the country.
Hersman says her team will spend a week to 10 days in the area looking at the bridge, talking to the truck driver whose vehicle hit it, and examining maintenance documents and previous accident reports.
Hersman does not expect the investigation to delay removal of debris from the river or work on a temporary solution to replace or repair the I-5 span.
